User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8
Build Identifier: Mozilla/5.0 (X11; Linux i686; rv:2.0b3pre) Gecko/20100803 Minefield/4.0b3pre

Crash with signature [@ StopRequest ] when a mozilla.cfg configuration file is specified via general.config.filename to set or lock preferences.
See also bug 576430

Reproducible: Always

Steps to Reproduce:
1. create "local-settings.js" with content pref("general.config.filename",
"mozilla.cfg"); in program directory Minefield/defaults/pref
2. create "mozilla.cfg" , byte-shifted with offset 13, in the Minefield program folder
3. Clear profile folder to make Minefield create a new profile folder

Actual Results:  
Minefield crashes immediately and doesn't start.



Expected Results:  
Minefield should start and process the preferences as set via mozilla.cfg

New bug filed as requested via bug 576430 comment 16.

Note that bug 576430 currently is preventing mozilla.cfg from working and "Failed to read the configuration file. Please contact your system
administrator." was shown instead of processing mozilla.cfg
